Reuniting father & son

This picture is the last time I seen my baby boy , before anything gets misunderstood, I know where my son is. But I’m denied access to him because his mother has been keeping him with her illegally and not allowing me to get time with him other then a FaceTime call or scheduling a time to come to her new place to see him for a couple of hours . Keep in mind she already is pregnant with another mans child and threatening me to be put on child support for both children NFS. If anyone knows me they know I never ask for help unless I REALLY need it . I honestly hate having to make a go fund me to see my son but I’m running out of options and I don’t wanna head down the wrong path. I’ve tried to get an online divorce but the case is apparently too complicated for them and my only option now is to save for a lawyer and get my rights with my son. This go fund me is mainly so I can put money into a account I can’t touch until it reaches the goal for the lawyer fees if anyone decides to help as well I’ll be very appreciative.
